Key Features:

Built with advanced materials and thoughtful engineering, this head gasket offers:

• Multi-layer steel construction for enhanced strength and durability
• Embossed outer layers coated with heat-resistant Viton rubber for superior sealing
• Compressed operating thickness of 0.036 inches for precise fitment
• Compatibility with both aluminum heads and blocks, as well as aluminum heads to cast iron blocks
• Resistance to corrosion and the ability to rebound under thermal cycling
• No requirement for additional sealants, simplifying installation
• Designed to withstand shearing forces between dissimilar metals
• Center shim layer of uncoated stainless steel customizable for thickness variations
• Embossed outer layers ensure a tight seal under high load and temperature conditions

Construction & Design:

The Cometic MLS head gasket features multiple embossed layers of high-grade stainless steel, providing exceptional strength and flexibility. The outer layers are coated with Viton, a fluorocarbon elastomer known for its excellent heat resistance up to 250°C (482°F) and chemical durability. This coating enhances the gasket’s ability to maintain a reliable seal in harsh environments and under varying surface finishes.

The gasket’s core shim layer is made from uncoated stainless steel, allowing for precise thickness control to meet specific engine requirements. This multi-layer design enables the gasket to absorb and compensate for the differential expansion between aluminum heads and cast iron or aluminum blocks, preventing leaks and maintaining engine performance.
